GRATING- DEVICE.

Application filed April 16, 1920.

To all whom it may concern:

Be it known that I, STnrANo' SANTILLI, a subject of the King of Italy, residing at Canton, in the county of Stark and State of Ohio, have invented a new and useful Grating Device, of which the following is a specification.

This invention relates in general to grating devices and more particularly to mechanism for holding and reciprocating the article to be grated and for feeding or ad vancing the grater toward the article to be grated.

The objects of the invention are to provide a grating device comprising a reciprocating clamp arranged. to hold the article to be grated, a grater and means for feeding the grater toward the clamp and for reciprocating the clamp in a plane parallel to the grater.

These objects, together with other ancillary objects are attained by providing a base having uprights at one extremity thereof, a block slidably mounted for vertical reciprocation upon said uprights, a clamping device carried by said block and arranged to be operated to clamp food or other articles to be grated therein, a perpendicular grater mounted for horizontal movement upon the base, a receptacle beneath the grater for receiving the grated substance and mechanism mounted upon the uprights for advancing or feeding the grater slowly toward the clamping mechanism and for reciprocating the block carrying the clamping mechanism in a plane parallel with the grater.

lVith these objects in view the invention consists in the novel construction and arrangement of parts, hereinafter described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form, proportions, size and minor details of construction may be made within the scope of the appended claims, without departing from the spirit or sacrificing any of the advantages of the invention.

The invention thus set forth in general terms is illustrated in the accompanying drawings forming part hereof, in which- Figure l is a longitudinal sectional view through a grating device embodying the invention.

Specification of Letters Patent.

Patented July 13, 1920. Serial No. 374,499.

F 1g. and

,Fig. 3 is a section on an enlarged scale on the line 3 3, Fig. 1.

A practical embodiment of the invention is disclosed in the accompanying drawings, forming a part of this specification in which similar numerals of reference indicate corresponding parts throughout the several views.

The form of the device illustrated in the accompanying drawings, comprises abase aving uprights 2 and 3 near one end thereof and preferably formed integrally with the base, said uprights being spaced sufiiciently to permit portions of the operating mechanism to be located therebetween as will be hereinafter described.

2 is a top plan view of the device;

Longitudinal side walls 4 are provided upon the base and extend from the forward end thereof to the upright 2, said side walls being provided upon their inner faces near their upper portions with horizontal guide grooves 5 within which grooves is mounted for horizontal movement, the frame 6, said frame being provided upon its rear side with the spaced vertical flanges 7, a grater 8 being fixedly connected to said flanges by any suitable means such as the screws 9.

Rearwardly disposed shields 10 are also fixedly mounted upon the flanges 7 and extend beyond the grater at each side to prevent the grated substance from falling outwardly at each side of the base and to direct the same downwardly into the receptacle or drawer 11, which is slidably mounted upon the base beneath the grater and provided with a sliding cover 12 which may be removed when the device is in operation.

Spaced horizontal shafts 13 are journaled through the uprights 2 and 3 and provided at their forward ends with screw threads 14 which engage threaded apertures within the sliding frame A pinion 15 is fixed upon the rear end of each of the shafts 13, each of said pinions meshing with an idle pinion 16 which idle pinions in turn mesh with an idle pinion 17.

One of the idle pinions 16 also meshes with an idle pinion 18 which in turn meshes with an idle pinion 19 mounted upon the shaft 20, which shaft is journaled through the upright 3 and is provided upon its forward end with a crank 21 pivotally connected at 22 with the link pivotally conected at 24: t0 the reciprocating head 25 mounted for vertical reciprocation within the guide groove 26 provided in the upright 2. j

The upright 2 is provided with a restricted slot 27 communicating with the groove 26 and a block 28 extends through said slot and is connected to the sliding head 25 by means of bolts 29 or their equivalents.

A pair of co-acting clamping jaws 30 are mounted upon the block 28 by means of the right and left screws 31, each of said screws beingjournaled in the block 28 and passing through threaded apertures in both of the clamping jaws. A pinion 32 is fixed upon each of the screws 31 and meshes with an idle pinion 33 which also meshes with a pinion 3 1 mounted upon the shaft 35, which shaft is provided with a hand wheel 36. Each of the clamping plates 30 is provided upon its inner face with the serrated teeth 37 between which the food to be grated is gripped.

A shaft 38 is journaled in the upright 3 and a hand wheel 39 provided with a crank 10 is fixed upon said shaft. If it is desired to operate the grater by power, a pulley 41 may be provided upon the shaft 38 to be connected by means of a belt with any suitable source of power, the handle 10 being of course'removed from the hand wheel. A. gear 12 is fixed upon the shaft 38 and meshes with the pinion 19.

When it is desired to operate the device to grate food or the like the slide 12 is withdrawn from above the receptacle 11. The food to be grated is placed between the clamping jaws 30 and the hand wheel 36 rotated to cause the teeth 37 to bite into the food holding it firmly between the clamp ing jaws.

The shaft 3S'is then rotated in the direction of the arrow shown in Fig. 3 and through the gear 12 and pinions 15, 16, 17, 18 and 19, the screw shafts 13 are rotated in a direction to slowly feed the frame 6 carrying the grater 8 toward the clamping jaws while at the same time the reciprocating head carrying the clamping jaws is reciprocated within the guide groove 26 by 23, which link is upright located gears meshing with said pinions means of the crank 21 and link 23 causing the food to be rapidly reciprocated across the face of the grater.

It will be evident from the above description and the accompanying drawings that 1s provided by means of which food may be easily and quickly and evenly grated and conveyed to a receiving receptacle with the minimumefiort on the part of the operator and without danger of injury to the operator.

I claim:

1. A grating device comprising a grater, a reciprocating head and automatic means for simultaneously reciprocating the head across the face of the grater and for feeding the grater toward the head.

2. A grating device comprising a base, an at one end of the base, a 'upon the base, a reciprohead mounted upon the upright and means for simultaneously reciprocating the head across the face of the grater and for feeding the grater toward the head.

3. A grating device comprising a base, an upright located at one end thereof, a frame mounted for horizontal movement upon the base, a reciprocating head mounted for vertical reciprocation upon the upright, clamping jaws upon the head, screw shafts for feeding the grater frame toward the reciprocating head, a crank for reciprocating the head across the face of the grater and means for simultaneously operating said screw shaftsand crank.

1. A grating device comprising a base, an upright located at one end thereof, a frame mounted for horizontal movement upon the base, a reciprocating head mounted for vertical reciprocation upon the upright, clamping jaws upon the head, screw shafts for feeding the grater frame toward the reciprocating head, a crank for reciprocating the head across the face of the grater, pinions fixed upon the ends of said screwshafts', a pinion upon said crank and a chain of for simultaneously operating the screw shafts and the crank.

In testimony that I claim the above I have hereunto subscribed my name.
